=== Propeller, Glow Plug and Fuel ===
==== Recommended propeller ====
Optimal diameter and pitch of the propeller needed depends on the model. The weight, or rather the wing loading and the aerodynamic clarity of the model play a role. Different requirements apply to slow high-wing aircraft (Piper – larger propeller with lower pitch) and to aerobatic "speedsters" (smaller diameter, higher pitch). It is likely that you will have to experiment a little to achieve a complete satisfaction. Using a propeller that is too small will force the engine to run at too high RPM. A propeller that is too large will "choke" the engine – the RPM will be too low. In both cases, this will lead to difficult carburettor adjustment and excessive engine wear with the risk of failure.

-Size: The diameter and pitch of the propeller needed for the AP09 depends on the application. Weight, size, drag, etc. are all factors in determining the correct size. Some experimentation will be necessary. Please keep your selection within the size parameters listed here:
